Newtons Laws of Motion and Simple Machines
Force and Motion
Force and Motion is full of many different topics. There are Newtons Laws of Motion and Simple Machines. If you look around you right now, you could find a whole lot of simple machines and some things that go with Newtons Laws. Did you know that the lid of a jar is an example of a simple machine? It is an example of a screw. There are 6 kinds of simple machines, and 3 of Newtons Laws. Look around and see what you can find!
Simple Machines
There are the 6 simple machines. A inclined plane, wedge, screw, lever, wheel and axle, and a pully. They help everybody around the world everyday, and they might not even know it! An example of an inclined plane is a ramp, an example of a wedge is a knife, an example of a screw is a lid of a jar, an example of a lever Is a see-saw, an example of a wheel and axle is a cars wheels, an example of a pully is a flag poles string that brings up the flag.
Newtons 1st law
Newtons 1st law of motion explains that objects in rest will stay at rest and objects is motion will stay in motion unless acted on by an outside force.
Newtons 2nd law
Newtons 2nd law of motion explains that the greater the force, the greater the speed,(acceleration) F=ma
Newtons 3rd law
Newtons 3rd law explains that for every actions there's a equal and opposite reaction.
Newtons laws
As I explained, Newtons laws are all around us! Like if you kick a soccer ball, it goes with all 3 laws. If you set a water bottle on a desk it goes with the 1st and 2nd law. But if you push it over, it will go with all 3! There are many things that go with newtons laws. Go and try some!
Did you know?
Did you know that a crane is a compound machine? A compound machine is a machine that has more that one simple machine. A crane has more than one simple machine, so it's a compound machine. If you look around you can find tons of compound machines!
Compound Machines
A compound machine is a machine with 2 or more simple machines working together. A crane is an example of a compound machine.
Force
Force is when you push or pull something. like when you push a door, or pull the door.
Motion
Motion is when your moving. Everyday you are moving, and evrything is moving around you. Why? Well, the Earth is moving, and the Milky Way is moving and everything is technically moving, even though it dosn't seem that way.
